4oz Hide Glue Granules for Strength and Clarity

Introducing Ragland's 1/4 pound (4oz) granulated hide glue, boasting a 251 gram strength and high clarity. This traditional adhesive has been trusted for millennia, proving exceptional for a variety of materials including felt, wood, leather, cork, cardboard, and paper. It is particularly beneficial in applications such as player piano restoration, luthier tasks, cabinet making, and much more.

One of the notable advantages of hide glue is its strong bonding properties, combined with the ability to be separated later if necessary, unlike many contemporary adhesives. For optimal use, it is recommended to heat the glue in a glue pot or double boiler, maintaining a temperature of around 140 degrees Fahrenheit. Be cautious and avoid using the small glue pots designed for hot glue chips, as they tend to heat the glue too much. Exceeding a temperature of 150 degrees Fahrenheit for extended periods can compromise the glue’s effectiveness by altering its protein structure and significantly weakening the bond.

For storage, dry glue crystals can last a long time if kept in a dry environment. Once mixed with water, glue should be refrigerated when not in active use. Should you observe any signs of mold or white spots in the glue, it is advisable to discard that batch and prepare a new one. A practical way to evaluate the effectiveness of hide glue is to bond some test wood pieces together and intentionally break the joint, allowing you to assess if the working time and bond strength meet your specific requirements.

Let's delve into the concept of gram strength: this refers to the amount of weight (in grams) required to depress a 1/2" plunger by 4mm into a 12.5% solution of the adhesive that has cooled to 10 degrees Celsius over 16 hours. It’s important to note that gram strength pertains more to the set time of the glue rather than the actual strength of the bond itself, although there are nuanced differences. For instance, a glue strength of 192 will offer a longer working time compared to one with a strength of 251; a lower number indicates a lengthier working period.

When considering clarity, there are two options: regular and high clarity. For projects where the visibility of glue lines is a concern—such as in cabinetry, instrument bodies (like guitars and violins), or when aesthetics matter—high clarity glue is recommended since it produces less noticeable glue lines. Conversely, for projects where visibility is not critical, regular clarity glue suffices.

Additionally, Ragland Piano hide glue comes with a silica gel pack to manage humidity during transportation, ensuring the glue remains in optimal condition. Each package includes clear instructions for best use, making it convenient for both professionals and hobbyists alike to experience the exceptional bonding properties of this high-quality hide glue.

In summary, Ragland's 1/4 lb. (4oz) granulated hide glue provides a reliable option for various applications, combining historical reliability with modern use considerations for superior results.
